My B Spec guy is hitting 193mph with it, how fast did you want to go? lol. This is on the Le Mans map, aka Circuit de la Sarthe. Once you get the HP up, you have to get the 20k transmission and adjust the top speed up. I think mine is at like 217. I would like to see some transmission tuning to make it hug the track better.
EDIT: Oops. Missed it was the LM you wanted a tune for, I have the regular car.
